X-Ray Image Noise Analysis and Static Noise Reducing Disposal
Hu Jia · Welded Pipe and Tube · 2007
Based on the analysis of human eyes vision features and image noise producing mechanism,this article explored keystone of zero average stable noise between frames,and provided exact resolution expression that could reduce image noise between frames and improve signal-to-noise ratio.Proved by practical examples,the system could effectively reduce image noise.This system was widely used in X-ray industrial TV inspection of SSAW pipe production line.
